Pernil Recipe Instant Pot: Puerto Rican Roast Pork with Mojo Crisp

This Instant Pot pernil brings authentic Puerto Rican flavors to your dinner table with a fraction of the traditional cooking time. The secret lies in the mojo marinade—garlic, citrus, and herbs—that infuses the pork shoulder with bold, vibrant taste.

I’ve tested this method repeatedly to ensure the meat emerges tender and juicy, while a quick broil delivers the crispy skin that defines pernil. The pressure cooker cuts hours off the process without sacrificing depth of flavor.

What you’ll get is succulent, fall-apart pork with a golden, crackling exterior, ready in under 2 hours. The aroma alone will have everyone gathering in the kitchen.

Serve with rice, beans, or plantains for a complete meal. Here’s how to make it.

The pork shoulder is non-negotiable here—bone-in, skin-on gives you that authentic texture and crisp. Costco has great prices for larger cuts, but any supermarket butcher can cube it for you. Look for good marbling if you’re buying a whole piece. The sour orange juice is key (find it at Latin markets or Walmart’s international aisle), but orange-lime mix works in a pinch.

No fresh oregano or cilantro? Dried at one-third the amount—just toast them first to wake up the flavors. Missing sour orange? Equal parts orange and lime juice gets you 90% there. The cumin can be skipped if you’re desperate, but it adds that earthy base. For the garlic, fresh is essential—don’t even think about the jarred stuff (it’s harsh and bitter).

Marinate the pork overnight if you can—12-24 hours is ideal. Leftovers keep 4-5 days in the fridge or freeze for 3 months. The mojo marinade also doubles as a killer sandwich spread (trust me, you’ll want extra).

Step-by-Step Instructions for Pernil

Here’s the method tested for foolproof results with crispy skin and tender meat.

Step 1: Create the Mojo Marinade

In a blender, combine the 12 cloves garlic cloves, 0.75 cup sour orange juice, 0.25 cup fresh oregano, 0.25 cup fresh cilantro, 1 tbsp ground cumin, 2 whole dried bay leaves, 0.25 cup olive oil, 2 tbsp kosher salt, 1 tsp black pepper, and 0.5 tsp red pepper flakes.

Blend until smooth, scraping down the sides as needed. The mixture should be fragrant with visible herb specks. This marinade infuses the pork with bright citrus and earthy spice flavors that define pernil. Pour it over the 3 lb pork shoulder in a large bowl or resealable bag.

Step 2: Marinate and Prep the Pork

Coat the pork shoulder thoroughly with the mojo marinade, ensuring it gets into every crevice. For best results, marinate for at least 4 hours or overnight in the refrigerator. The longer it marinates, the deeper the flavor penetration.

When ready to cook, remove the pork from the marinade (reserve the marinade) and pat the skin dry with paper towels. This step is crucial for achieving that signature crispy skin. Score the skin in a crosshatch pattern, cutting about ¼ inch deep to help render the fat and allow the marinade to penetrate.

Step 3: Pressure Cook the Pork

Set your Instant Pot to the sauté function. Add the reserved marinade and 1 cup water to the pot. Place the pork shoulder skin-side up on the trivet. Secure the lid and set to high pressure for 60 minutes.

Once the cooking time is complete, allow a natural release for 15 minutes, then quick-release any remaining pressure. The pork should be fork-tender and easily pull apart. Carefully remove the pork and transfer to a baking sheet.

Step 4: Crisp the Skin

Preheat your oven to 425°F. Brush the pork skin with some of the cooking liquid from the Instant Pot. Place under the broiler for 5-7 minutes, watching closely to prevent burning.

You’re looking for the skin to puff up and turn deep golden brown and crispy. The meat should already be fully cooked from the pressure cooking, so this step is purely for texture and appearance. Rotate the pan as needed for even browning.

Step 5: Rest and Serve

Remove the pernil from the oven and let it rest for 10-15 minutes before shredding or slicing. This resting period allows the juices to redistribute, ensuring moist, flavorful meat.

Drizzle with some of the cooking liquid and the 0.25 cup lime juice for a final bright finish. Serve with rice and beans, or use in sandwiches for a true Puerto Rican feast. The skin should be crackling crisp while the meat remains incredibly tender.
